Abstract: Through the bending test of the composite components for a glass fiber fabric reinforced concrete formwork components， the paper discussed the influence on the overall bending strength of overlapped beams of different treatments of the TRC formwork，different after pouring concrete intensity and different layer number of textile． The result showed that TRC panel did not need special treatment and it could work together with after pouring concrete very well． For the same kind of TRC formwork， the lower concrete strength， the more obvious enhancement effect on its bending strength． Textile has areinforcedconstraint function， its participation is benificial to the improvement of the component bending strength and the number of the fibres is not the more the better，but it needs the optimal number of fibres．
